WINDOW CLEANERS S AFETY' HARNESS.

Application filed October 31,1921. Serial No. 511,847.

To all 10 7mm i may concern:

Be it known that L'HENRY J. Gnins'r, a citizen of the United States," residing at Chester, in the county of Delaware and a State of Pennsylvania,' have inventedcertain new and useful Improvements in Window Cleaners Safety Harness, of which the following is a specification.

One object of my invention is to provide an improved device which can be used by a person while cleaning a window; said device boil- 1g so constructed that it will prevent the person from falling outiof the window and at the same time will not interfere with the necessary movements of the person in order to properly clean the window;

Anotherobject is to so construct my improved device that it can be readily attached to or removed from both the person and a portion of the window frame without requiring any fixtures upon the window frame A further object is to so make my im proved device that it will be durable and can be easily manufactured. i i I iii? These objects, and other, advantageous ends which will be descrioed hereinafter, I attain in the following manner, reference being had to the accompanying drawings in which v Figure 1 is a perspective view of a device made in accordance withmy invention.

Figure 2 is a side elevation of said device showing the same attached to a person and to a portion of a window frame; said person and window frame being illustrated in clotand-dash lines,

Figure 3 is an enlarged fragmentary view partly in section showing one of the hooking devices and the manner of attaching the same to a belt which forms a part of my invention,

Figure 4 is a viewof the same general character as that shown in Figure 3 illustrating all of the portions in section Figure 5 is a perspective view of a portion of one of the hooking devices illustrating the same before thehook is finally secured in position within the pocket provided therefor,

Figure 6 is a fragmentary section taken on the line 66 of Figure 5 and illustrating the same after the hookhas been'secured by sewing within its casing,

Figure 7 is a sectiontaken on the line 7--7 of Figure 5, l

Figure 8 is a section taken on the line 8-8 of Figure 5,

Figure 9 is a perspective view showing a slight modification in themanner of securing the .hook, and a Figure 10 isa perspective view showing a modified form of hook which I may employ.

Referring to the drawings and particularly to Figures 1 to S inclusive, my ii'i'iproved device includes belt 10 which may be made of flexible strap material such for example as canvas or heavy duck. This belt includes an adjustable buckle 11 by means. of which it-can be varied in dialneter in order to fit persons of various waist dimensions.

In addition to the buckle'll I preferably provide buckle 12in the front for a purpose hereinafter described and srovide an apron-13 which is connected to the belt in the front by means of loops i i which are secured to the apron and are positioned at opposite sides of the buckle 12; it being noted that the belt passes through the loops l4. Straps 15 are secured adjacent their ones to the belt 10 at positions at opposite sides of the buckle 12; said straps forming upright channels 16 through which looped portions 17 of flexible arms or tension members 18 extend. These looped portions 17 include adjacent buckles 19 whereby the length ofthe can be varied. The arms 18 are preferablyinade of strong canvas or heavy duck and at their outer free ends inolude'pockets 20. .hese pockets. as shown for example in Figures i, 5, 6 and 7, are preferably produced by weavin the arms of integral tubular formation of substantially flat cross section shown in Figure 7. \Vithin these pockets 1 insert strong hooks 21 which are preferably made of non-corrodible metal which is of comparatively wide straight and flat cross section and in. applying the hooks they are inserted within the pockets 20 after which the upper ends 21 of the pockets are sewed by a stitching 532 as shown in Figure 6 in order to enclose the hooks within the pockets. In order to cheaply form the pockets the entire arms 18 can be made of tubular fabric, such for example as shown in Figure 4, and a siit 23 can be cut through one thickness as shown in Figure 5 to form an opening to insert the books after which the stitching 22 can be inserted. I

If desired,as shown in Figure 9, thehooks can be secured without the formation of the integralftubular arms by making the arms of a single thickness as shown at 18 and folding the outer ends so as to include and embrace the hooks after which the arms can be stitched along their side edges and end 24 by sewing the same along the lines-indicated at 25 so as to form a casing for the hooks. It will be noted that in both of the forms of my invention the hooks are covered by the flexible material ofthe arms and that the cross section of the hooks and arms is approximately fiat and comparatively wide.

In the use of the device, the belt 10 is placed around the waist of the wearer, as shown in Figure 2, and the buckle 11 can be used for adjusting the belt so as to comfortably but securely fit the waist of the wearer. The arms 18 can be moved forwardly at an incline so as to embrace the inner edge of the window sill 26 while the person can sit on the window sill as clearly illustrated in Figure 2. Any necessary adj ustinent between the forward portion of the belt and the portion 26 of the window sill can be secured by means ofthe buckles 19 and when in use tension will be applied to the arms and this tension will be resisted due to the engagement of the hooked portions of the arms with the part 26 of the window sill or ledge. in order to provide adjustment of the distance between the armslS, the buckle 12 can be manipulated so that the arms 18 can be moved closer together or further apart as desired. This adjustment can be attained without disturbing the apron 13 for the reason that the portions of the belt will merely slide through the loops l4. 7

The apron is preferably provided with pockets 27 in which can be conveniently placed articles necessary for use in cleaning th window such for example as cloths, sponges, chamois or the like and the articles can be kept within reach of the window cleaner.

By having the comparatively wide hooked portions on the arms 18, a secure bearing is provided so that it is practically impossible for the hooks to rock laterally when in engagement with the inner edge of the Window sill or ledge. If desired the hooks 21 can be provided with a reinforcing rib between their side edges as shown at 28 in Figure 10 and this rib can be made by stamping or )ressin the material of the hooks so as to reinforce the same and in so making the hooks they can be stamped out of sheet metal or can be cast. It will be further noted that the casing which forms the cover for the hooks serves to prevent injury to the window sill and keeps the latter 'from becoming scratched or marred in any manner.

While I have described my invention as taking a particular form, it will be understood that the various parts of my invenlnon may be changed without departing from the spirit thereof, and hence I do not limit myself to the precise construction set forth, but consider that I am at liberty to make such changes and alterations as fairly come within the scope of the appended claims.

. Having thus described my invention, what I claim as new and desire to secure by Letters Patent is 1. A device of the character described in cludin a belt; supportingmeans attached to said belt and having curvedmeans for embracing the edge of a window frame and being readily removable therefrom; adj usting means for varying the length of the frontpart of the belt between said supporting 'means; and means for varying the length of the belt independently of said firstadjusting means; substantially as described.

2. A device of the character described including a portion adapted to be attached to a person; nd supporting arms leading from said portion and having hooked parts arranged to embrace the edge of a window sill, said arms each comprising a tubular casing of flexible material and a hook of rigid material enclosed in the free end of said tubular casing.

3. A device ofthe character described including a belt; arms attached to said belt and having hooked portions; adjusting means for varying the length of the portion of said belt between said arms; and means for varying the diameter of said belt independently of said first adjusting means; substantially as described. 7

4. A device of the character described-including a belt; arms attached to said belt 5. A device of the character described in cluding a belt; arms attached to said belt and having rigid hooked ends covered with flexible material for engaging the window sill; adjusting means for varying the length of the belt portion between said arms; a pocketed apron provided with supporting loops through which said adjustable belt portion slides; and adjusting means for varying the length of said belt independent of said first adjusting means; substantially as described. 7 V I In testimony whereof I have signed my name to this specification, in the presence of two subscribing witnesses.
